You can put this solution on YOUR website!
This is what I call Advanced Trinomial Factoring again.\r
\n" ); document.write( "\n" ); document.write( "5x2+13x+6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First times First MUST be:
\n" ); document.write( "(5x____)(x____)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The Last times Last has several possibilities. It could be 1*6 or 6*1. It could be 2*3 or 3*2. You need to get a combination of numbers such that the OUTER times OUTER plus the INNER times INNER will add up to the middle term which is 13x. The combination that works is 3*2. See below:
\n" ); document.write( "(5x+3)(x+2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice that the OUTER times OUTER would be 5x*2 = 10x, and the INNER times INNER would be 3*x = 3x. This adds up to 13x, so this is the answer:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(5x+3)(x+2) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R^2
